Hydrogenation of olefins over hydrotreating catalysts.effect of the olefin structure

摘要

Because of increasing environmental concern and pertaining regulations,hydrotreating has become more and more important in refining with the objective of removing as much as possible of the sulfur impurities from petroleum products.In connection with the specific requirements of the hydrotreating of FCC gasoline,the selectivity of hydrotreating catalysts in hydrodesulfurization with respect to the hydrogenation of olefins has to be controlled and if possible improved in order to limit the octane rating loss and references there in.Several factors can influence this selectivity,the presence of Co and Ni promoters in particular.
